Additional information

The environmental effects of the hydrocarbons, C9-C12, aliphatics, 2 -25% aromatics has been defined by a series of studies on fish, Daphnia, and algae.  Results of the key studies showed that this substance would exhibit LL50 or EL50 values (based on loading rate of water accommodated fractions) of 10-30 mg/L (fish), 10-22 mg/L (Daphnia), and 4.1 and 4.6 -10 mg/L (for both growth and biomass of algae).  All of these studies were conducted using Water Accommodated Fraction (WAF) methodology because of the complex composition and limited water solubility of constituents in hydrocarbons, C9-C12, aliphatics, 2 -25% aromatics.

Chronic toxicity to fish was estimated to be 0.13 mg/l (NOELR based on growth). Studies on invertebrates and algae found NOELR of 0.28 mg/l (based on reproduction) and 0.16 / 0.22 mg/l (based on algal biomass) respectively.

Conclusion on classification

For purposes of environmental classification, this substance falls within a 1 to 10 mg/L range for acute aquatic toxicity. This substance is considered to be readily biodegradable.
